Let’s say that Schwartz doesn’t win the RAT nomination (I think that she will, but whatever). In that case, unless a viable Republican candidate beats Corbett in the GOP primary, the choice in November will be between Corbett and someone just as liberal on economic issues as Schwartz. And do you think that the GOP state legislature will be able to pass any tax cuts over the Democrat governor’s veto?

Either take out Corbett in the primary with a candidate who can win the general (he certainly can be more conservative than Corbett, but he can’t be some nobody with no record), or else support Corbett in the general; otherwise, a liberal Democrat will be governor.
